The title compound was prepared from 5-cyclohexyl- 1,3-dihydro-1-methyl-3(R,S)-[(4-nitrophenyloxycarbonyl)amino]-2H-1,4-benzodiazepin-2-one (0.3 g, 0.69 mmol), triethylamine (96 μl, 0.69 mmol), dimethylformamide (6 ml) and 1-(thiazol-2-ylaminosulphonyl)-3aminobenzene (0.19 g, 0.76 mmol) using the procedure described in Example 11, Step 4. The product (125 mg, 33% ) was afforded as a cream solid after trituration with methanol. mp 230° C.
